Put the straw and/or dung into a pillow case, submerge in pot with water with a weight on top at 170°F for one hour.
Donīt exceed 170°F, check the temperature frequently with a thermometer.
After 1 hour take the pillow case out and use your oven rack on top of the sink. Put it on that and let it drain for several hours. When it has cooled down somewhat , give it a squeeze, as hard as you can. Then fluff it up and leave on the rack to drain/dry out a bit more.
After itīs cold (might take several hours) you can spawn it.
